Wireless diagnosis and monitoring system of sensor network from civil structures

This paper is focused on the development of a wireless device used in diagnosis and monitoring of sensors networks from civil structures like hydro-energetic buildings. Those constructions are monitored with sensors and measurement systems spread over the entire construction's body. The measurement systems are connected through a RS485 network. The entire structure forms a data acquisition system that is usually controlled by a software application that runs on a computer. A daily management activity in hydro-energetic buildings consists in an automatic and a manual data collection. At the physical layer, in real life, the measurement devices and RS485 networks can be affected by a set of malfunctions that are dangerous signal integrity for the safety of a human operator. For that reason a manual measurement device based on wireless technology is useful. The issues of signals integrity of RS485 lines are detected with an electronic device that is connected to the lines. In additional, using communication protocol the data from each sensor can be collected. The panel interface of the human operator is a software application that runs on a smart mobile device that uses Bluetooth communication [2]. In the last years the mobile software applications has been greatly increased in industry [1]. By using a software application and a wireless mobile device a diagnosis and monitoring system is developed which is more safety and has a vast development space [3].
